Have 2007 All American with a Cummins. Has push button pad for the transmission. The key pad has like a leaning plus sign. When we ran the allison program it said no power to console. When we would shift the transmission, it would go blank, but the mode light is on. Bus will go into gear but not show which gear. we had a spare console and nothing changed. Didn't give a code but showed 26-11 . Last time I had on with issues was the power wire. Where should I look. I checked the relays and good. Fuses good

I am checking the bus out this morning and found a lot of transmission fluid gone. Could that be the problem with no controller on the dash?

I forgot to write back it was a wire issue from the control to the ECM so we just ran a new wire
